The different products available in the market for lidding generally are aluminium foil/PE or PET/PE structures. However, BOPP used for lidding applications scores over its counterparts in terms of sustainability, yield and therefore cost, better aesthetics and fold/flex resistance.

 

These films are available in white opaque cavitated and semi-transparent variants. The BOPP film based lids are safe for direct food contact as no solvent is involved and ingredients involved in the manufacturing of this product are approved by the FDA. The films offer excellent peelability, printability with water and solvent-based inks and high aesthetic appeal. The films offer good moisture barrier properties and films to cater high barrier needs are also available.

 

The films can be easily die-cut and punched and display good stiffness for dispensing.  The films can be used for both inline and offline lidding processes. The product is available in standard thickness of 50, 75 and 85 microns. Other microns are also possible on demand.

 

Pankaj Poddar, CEO, Cosmo Films, said “We saw both end-consumers and printers facing challenges while using unit packs especially for packaged drinking water. The consumers invariably found it challenging to peel the pack without spilling and the label printers faced issues with finding the right adhesives for heat sealing of the lidding film. To bridge this gap, we have developed a cost-effective product where all that the printer needs to do is to print, die-cut and supply the film to the brand. The film can also be sealed at lower sealing temperatures of 140-150 degrees.”
